Specification of Letters Patent.

Patented @ct. 22,1912.

Application filed May 21, 1912. Serial No. 898,774.

To all whom it may concern:

Be it known that I, VINCENT J. DANIELS, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Door or Vindow Lock, of which the following is a full, clear, and exact description.

This invention relates to devices for locking or securing a window, door or other movable object in any desired fixed position. Such devices are commonly used for the purpose of locking a door or window shut when the same is not furnished with a regular locks, and among the objects of the invention is to provide a device of this gen eral nature which may be easily carried in ones pocket or suitcase when away from home.

The foregoing and other objects of this invention will hereinafter be more fully described and claimed and illustrated in the drawings accompanying this specification in which like characters of reference indicate corresponding parts in all the views, and in which- Figure l is a vertical longitudinal section of the device in operative position; Fig. 2 is a perspective view of the same; and Fig. 3 a side elevation showing the device folded.

In the general aspects of this invention it is of the same character as the device patented by John H. Daniels, on May 9, 1876, but the present improvement makes the device into a practical form because certain loose and easily lost parts are now dispensed with.

Referring particularly to the accompanying drawings, the device will be understood to comprise a substantially flat base plate 10 to which is hinged at 11 a movable plate 12 as in the previous patent referred to. When it is desired to look a door, indicated dia grammatically at D, inv a closed or open position, the device will be slipped into the space between the door and the floor F on the proper side of the door to prevent movement thereof, and then while the device is in the position indicated in Fig. 3, by strik ing upon the plate 12 with ones heel or the like, the spur 13 will be caused to enter the floor sufficiently far to secure the lock in position. The spur 13 may be located at any convenient point in the plate 10 and may be secured therein conveniently by upsetting the upper end thereof after passing through the plate. The point 13 is preferably directed slightly toward the direct-ion in which the door would move but for the lock. After placing the lock, as above described, the plate 12 will be lifted substantially into contact with the door and the short brace member 14 pivoted at 15 to the base 10 will. then be swung upon its hinge upwardly from the position shown in Fig. 3 into interlocking engagement with the plate 12 in any suitable manner. As shown, the brace 14: is provided at its upper end with a tongue or projection 16 adapted to extend through a slot 12 of the plate 12, maintaining the plates 10 and 12 at an acute angle with each other. The brace 14. is provided adjacent the tongue 16 with a shoulder 14: against which the plate 12 strikes when in opera tion. It will, therefore, be practically impossible for the brace 14 to slip out of interlocking engagement with said plate 12, whereby it will be assured that the wedge thus formed by the plates 10 and 12 will prevent the door from swinging undesirably, the wedge being held in place, as indicated above, by the spur 13.

It will, of course, be apparent that the same device may be applied to a window frame to secure one of the sashes in any posit-ion. It will be understood, furthermore, that the relative sizes and proportions of the several parts may be varied to any desired extent, and that they may be made of any suitable materials without departing from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

The herein described door lock comprising, in combination, a base plate having a spur to secure it in position, a second plate hinged at one end to one end of the base plate, said second plate having a slot through its opposite end, and a short brace member hinged to the opposite end of the base plate having a tongue extending through said slot in the second plate and a shoulder engaging said second plate, wherename to this specification in the presence of by the base plate and second plate will be an two subscribing witnesses.

ranged at an acute angle with each other T i and formed into a substantial wedge adapt- CENT DANIELS ed to fit between the door and the floor, sub Witnesses: stantially as set forth. GEO. L. BEELER,

In testimony whereof I have signed my PHILIP D. RoLLHAUs.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
